iRZ C1 - Remote data collection systemGeneral questions dispatch Use of mobile services in dispatching systems of resource accounting has long understood as an integral part of these systems. Communication technology is continuously evolving, with the highest standards are more advantageous and preferred. So, once considered the only possible technology CSD, now receding into the past, giving way to GPRS/EDGE/3G standards. Connection CSD (dial-up connection between two nodes) in the GSM networks are more or less stable only works inside the network of an operator of one region and can not be guaranteed outside these networks. CSD connection is billed hourly, which does not have an unbroken connection to remote sites. For a survey of remote sites need to connect in series with each node. In periods of high load telephone network voice calls CSD connection is not available, so you have to survey at night. GPRS - a modern technology of data transmission than the CSD. It allows you to organize the TCP/IP connection is charged on actual traffic and allows you to organize a continuous connection. However, it uses the same time slots in GSM traffic, and voice calls. It imposes the same restrictions on time polling devices that CSD. In the wireless dispatch object used GPRS connectivity, built over topologies "point-point"or "Star", which requires a fixed external IP-addresses. For them will be charged a considerable additional monthly fee. Based on GPRS connection emulation virtual COM-ports. This option could lead to difficulties in control when the amount of time in a constant connection of devices over a hundred pieces. Another alternative is to use tariffs of operators GSM, offering a private organization of local networks in GPRS/EDGE/3G with assignment of local static IP-address to each subscriber in the network. This solution enables you to use the VPN service provided directly by the operator, but requires the purchase of the corporate rate and leads to significant financial costs. In addition, at the remote sites is not enough just use the GSM-modem. Need to use a router or other device capable to communicate with the operator.

Introducing the system iRZ C1 We offer a qualitatively new solution for wireless dispatch and telemetry. Our product eliminates these shortcomings of other solutions. iRZ C1 – system designed for remote dispatching remote sites through networks GPRS/EDGE/3G. iRZ C1 system to replace the widely used in GSM CSD connection to connect via TCP/IP mode GPRS/EDGE/3G, which is economically and technically justified. Incorporating the positive side to GPRS, 3G standard does not use frequency voice communication that allows you to have contact with objects at any time and at great speed. Application of 3G communication systems provides a more reliable communication channels than those offered in GPRS mode and, moreover, CSD. Cost GPRS/EDGE/3G compound is charged only on the used traffic and does not depend on time (unlike the CSD), which allows you to have an indissoluble connection with all devices and if necessary to obtain data in real time. The transmitted information is encrypted cryptographically algorithms used in banking and other mission-critical networks. In addition, iRZ C1 does not require the use of tariffs to an external fixed or dynamic IP-address, and, consequently, additional monthly fee. Simply connect any SIM-card with access to the data transfer via GPRS. Moreover, our device can work with two SIM-cards, optimizing their tariffs, as well as backing up a system of two providers of mobile communications. iRZ C1 is not a virtual COM-port, although it can be configured for these purposes, and provides a link to a dedicated internal IP-address. The software system allows iRZ C1 multiply the number of connected devices in comparison with systems that use virtual COM-ports. The system iRZ C1 uses OpenVPN, without requiring the operator to use its special corporate rates and services. Used only Internet access service. Composition iRZ C1 consists of a device iRZ RC1, being connected to a remote object and the software installed on the server for collecting and processing information. The whole system is localized at the its owner. Information is drained directly to the server the owner of the system without any intermediaries. Installation of communication and management performs exactly iRZ RC1. A router running the Linux operating system and has flexible settings, allowing you to specify: mode of connection to the server (continuous or scheduled), the algorithm switching SIM-cards and much drugoe.V as software that performs the interaction of the remote host with the program management of the node (For example, the program scheduling teplovychisliteley) used among OpenVPN. Its implementation is available for various operating systems including Windows. OpenVPN creates encrypted channels such as point-to-point or server-based clients from one computer or similar computing units. OpenVPN comes with each device iRZ RC1, but must also be installed on the server dispatch. This environment is free of charge and can be freely obtained from the server http://www.openvpn.net. Using a standard OpenVPN TCP and UDP protocols allows it to operate in situations where the telecommunications operator blocks certain VPN protocols. OpenVPN creates a virtual private network and remote sites (iRZ RC1 with attached probe) are parties to this network. Each iRZ RC1 is assigned its own internal static IP-address. The program device control (the program scheduling teplovychisliteley) recorded these IP-addresses. Thus, IP-addresses, which assigns communication operator remote devices during a communication session is in no way affect the operation of the entire complex. Static internal IP-address is assigned to each device iRZ RC1 when installing it on an object. This address will be entered into the program supervisor. When connecting to a remote node to the server dispatch OpenVPN creates an encrypted IP tunnel. Data is transferred along this tunnel, where they are securely closed and impersonal. At the remote ends of the system for external objects (eg, heat meter) uses the standard RS-232, RS-485 and USB (for the possibility of obtaining additional COM-port). In addition, under the order may be implemented additional interfaces. The system allows you to combine on a single server to work with sensors from different manufacturers. In addition, for data visualization is one program that offers a manufacturer of sensors themselves (for example, teplovychislitelya CGT-7 program VKT7Easy2 or OPC_VKT7), or any other (for example,«Clever energy monitoring»),maintenance of sensor used. Recommend the use of scheduling software that use to work with TCP, though there is an opportunity to work with virtual COM-port. Principle of operation Router iRZ RC1 on power alone establishes a connection to the server collecting data on TCP/IP protocol and subsequently monitors the link, and when it performs failure recovery connection. Dispatcher or dispatch program, using established TCP/IP connection to exchange data with a remote node. Dispatch program polls the remote node on the internal IP-address of the VPN network. OpenVPN on Wednesday created a tunnel to exchange data in encrypted form to a remote device iRZ RC1, which converts the data to the RS232, RS485 or USB to connect to the terminal device. Figure 1 shows the scheme of interaction within the system iRZ C1. Number of sets (Teplovychislitel / device iRZ RC1) can be virtually unlimited.

Description iRZ RC1: iRZ RC1 has two slots for SIM-cards and can switch between them automatically or on command via the web interface. Automatic switching occurs or a loss of communication with the operator, or by schedule. In the case of switching on loss of communications can return to the priority SIM-card.
